在使用CefSharp Nuget包的CLR应用程序上获取鼠标单击坐标

问题描述

我要获取用户在页面上单击的位置的坐标。基本上我希望在ChromiumWebBrowser页面上鼠标事件。

我正在构建一个MFC MDI CView派生的浏览器应用程序，该应用程序使用对CLR的引用。为此，我点击了链接 https://www.youtube.com/watch?v=uBvDK6LE4XM。

我正在使用nuget包cef.redist.x86（3.3325.1758），cef.redist.x64（3.3325.1758），CefSharp.Common（65.0.0-pre01），CefSharp.WinForms（65.0.0-pre01 ）。

该实现有一个toolstripcontainer，我正在按以下方式加载浏览器：

ChromiumWebBrowser^ browser;
browser= gcnew ChromiumWebBrowser();
browser->Load("http://google.com");
this->CefToolStripContainer->ContentPanel->Controls->Add(browser);
browser->Dock = DockStyle::Fill;
this->AddressToolStripTextBox->Text = "http://google.com";

我能够获得OnFrameLoadEnd之类的事件。但是当我尝试获取鼠标事件时，执行此操作则什么也没发生

this->browser->Click += gcnew System::EventHandler(this,&clr_cefbrowser::CefBrowserCtrl::OnClick);

对于我添加的其他控件（从contentpanel中删除浏览器后）触发了click事件，但对浏览器不触发。下面是实现的完整代码。

}; }

void clr_cefbrowser::CefBrowserCtrl::OnClick(System::Object ^sender,System::EventArgs ^e)
{
    MessageBox::Show("Click Event");
}

在“我的视图”课程中，我有

CWinFormsControl<clr_cefbrowser::CefBrowserCtrl> m_CefBrowser;

然后我使用BEGIN_DELEGATE_MAP和MAKE_DELEGATE得到frameloadend事件。我真的不确定如何从这里继续。
